It\u2019s pretty rare to find organ meat on the dinner table in most American households today, but 90 years ago, the earliest editions of\xa0The Joy of Cooking\xa0contained dozens of recipes for liver, sweetbreads, and even testicles. For much of history, offal (as organ meat is called) was considered the best part of the animal\u2014so what happened? Why are brains banned in the UK and lungs illegal to sell in the US, and why are Scottish haggis-makers up in arms about it? And the question we\u2019re sure you\u2019ve all been pondering: What do testicles taste like?\n\nWith the help of Jonathan Reisman, author of the new book\xa0The Unseen Body: A Doctor's Journey Through the Hidden Wonders of the Human Anatomy, we explore how the vital functions of various animal organs affect their flavor and taste. Jon\u2019s wife, Anna Wexler, also an academic and a writer, joins us to impart the wisdom she\u2019s gained from years as a judge at the World Testicle Cooking Championship (aka Test Fest). We learn about the culinary history of offal from cookbook author Jennifer McLagan, and butcher Sam Garwin comes over to help us prepare up a massive organ meat feast: a Norwegian heart and lung pate (yes, we scored some lung!); a Georgian testicle stew; rabbit, chicken, and beef liver and onions; and breaded, fried lamb brains. Listen to find out which one we liked best, and which ones were just plain offal! (Sorry, we couldn\u2019t resist.)\nLearn more about your ad choices. Visit podcastchoices.com/adchoices
